INTAKE-MANIFOLD r'on n'xrLosrvn-nncmns.

Specification of Letters Patent.

Application filed May 19, 1910. Serial No. 562,280.

To all whom it may concern:

Be it known that I, Josnrl-t C. \V. VAN Brannon, a citizen of the UnitedStates of America, residing at Detroit, in the county of \Vayne andState of Michigan, have invented certain new and useful Improvements inIntake-Manifolds for Explosive-Engines, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to a manifold'intake for explosive engines, andmorepart-icularly to an arrangement thereof which provides for an evendistribution of carbureted air to the several 0 linders of an engineandto means for t rottlin the fuel supply without changing the carureter or mixing device.

The invention consists in the matters hereinafter setforth, and moreparticularly pointed out in the appended clalms.

Referring to the drawings,'Fi ure l is a view in elevation of'a manifoldintake that embodies features of the invention; and Fig. 2 is a viewiii-longitudinal section partly broken away and enlarged, of the device;

In the drawings an outer tubular casing 1 is permanently closed at eachend and is provided with a plurality of regularly disposed outlets 2each provided with flanges 3 by which they ma be secured to inletopenings of a multi-cy inder engine. The casing has a central transversecylindrical body 4 with a pair of diametrically disposed exteriornipples 5 in axial alinement with the tubular casing.

Distributing tubes 6 are secured attheir inner ends in the nipples 5 andat their outer ends engage bosses 7 on the inner faces of the casinends8 or are otherwise permanently close and secured at their outerextremities to the casing. The inner inlet ends of the distributingtubes 6 .are adapted to register with a pair of diametrically oppositeports 9 formed in a hollow closure 10 that is rotatably secured in thecylinder body 4. The upper end of the closure is closed and is providedwith a stem 11 that extends through a cap 12 detachably secured on thebody end. The lower end of the closure is open and registers with aninlet opening 13 in the casing. Each distributing tube 6 hasa lateraloutlet 14 near its outer extremity.

When in use, the indrawn' vapor from a carbureter or other like deviceenters the inner tubes of the manifold and passes to the outer endsthereof into the outer casing from whence it is drawn in order by theengine cylinders. The manifold thus becomes a mixing chamber owing tothe length of the passage through which the vapor is drawn and insures aconstant quality of fuel, as the throttling is done by the manifoldvalve so that the carbureter or other primary mixing device is notdisturbed or readjusted when once set. Furthermore if there is anycondensation of the vapor, it takes place 1n the inner tube and thedrops settle therein and are taken up again by the passing current sothat-there is no flooding or other similar disturbance.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of the invention and I do not wish to limitmyself to any particular form or arrangement of parts.

That I claim as my invention is 1. A manifold intake for enginescomprising an outer cylindrical casing closed at its ends and providedwith a plurality of lateral outlets, a transverse cylindrical bodyPatented Jan. 3, 1911.

centrally disposed in the casing tprovided at one end with an inlet, apair 0 oppositely disposed distributing tubes in the casing rovided withintake ends opening into the lnterior of the body and lateral outlets attheir outer ends, and a valve closure rotatably seated in the body andadapted to control communication between the casin inlet and the inneropen ends vof the distributing tubes.

2. A manifold intake for engines comprising an outer cylindrical casingclosed at each end provided with a plurality of lateral outlets, acentral transverse cylindrical body centrally disposed in the casing andprovided at one end with an inlet and also with lateral outlets insubstantially axial alinement with the casing,a air of oppositelydisposed distributing tu es in the casing whose inner inlet ends areconnected wit the lateral openings of the body and whose outer ends havelateral outlets, and a valve closure, rotatable in the body having aninlet port in register with the body inlet, and lateral outlet portsadapted to register severally with the inlet en tubes.

3. A manifold intakefor engines comprising an outer cylindrical casingclosed at each end and provided with a plurality of lateral outlets, atransverse cylindrical body cens of the distributing axial alinementwith lnner. en s are connected to the body nipples end and provided witha .in thefibody and adapted to control com trally disposed in the casingand rovided at one end with an intake opening, ollow ni ples extendingradially from .the body n the casing, a pan of oppositel disposeddistributing tubes whose and whose outer ends each have a lateraloutlet, and a valve closure rotatably seated munication between the bodyinlet and the distributing tube inlet ends.

4. A manifold'intake for engines comprising an outer cylindrical casingclosed at each plurality of lateral outlets, a transverse cylindricalbody centrally disposed in the casing and provided at one end. with inpresence 0 an intake opening, a pairof op ositely disposed hollow niples on the ho y in axial alinement with tliia'casing, a pair of.dlstributing-tubes each secured at its inner end in a nipple of the bodyand prov1d ed at its outer end with a lateral outlet, a cylindricalclosure journaled the body and provided at one end with an intake portand with lateral outlet each adapted 25 to register with one of p eopemngs, and a stem for manipulatin e closure.-

In testimonfy whereof I afiix' my signature two witnesses.
